    CKEditor Sample &mdash; Producing HTML Compliant Output
</h1>

<div class="description">
    <p>
        This sample shows how to configure CKEditor to output valid
        <a class="samples" href="http://www.w3.org/TR/html401/">HTML 4.01</a> code.
        Traditional HTML elements like <code>&lt;b&gt;</code>,
        <code>&lt;i&gt;</code>, and <code>&lt;font&gt;</code> are used in place of
        <code>&lt;strong&gt;</code>, <code>&lt;em&gt;</code>, and CSS styles.
    </p>

    <p>
        To add a CKEditor instance outputting legacy HTML 4.01 code, load the editor using a standard
        JavaScript call, and define CKEditor features to use the HTML compliant elements and attributes.
    </p>

    <p>
        A snippet of the configuration code can be seen below; check the source of this page for
        full definition:
    </p>
	<pre class="samples">CKEDITOR.replace( '<em>textarea_id</em>',
	{
		coreStyles_bold	: { element : 'b' },
		coreStyles_italic : { element : 'i' },

		fontSize_style :
			{
				element		: 'font',
				attributes	: { 'size' : '#(size)' }
			}

		// More definitions follow.
	});</pre>

            <strong>CKEditor requires JavaScript to run</strong>. In a browser with no JavaScript
            support, like yours, you should still see the contents (HTML data) and you should
            be able to edit it normally, without a rich editor interface.
